Inspection, investigation example 3 jifunsagurikizukensa

jifunsagurikizukensa becomes the laboratory procedure using magnetism. One becoming subject to examination becomes the materials drawn to a magnetic body, I mean magnetic force. A kind is in jifunsagurikizukensa, but comments on the law between poles adopting in us.

With jifunsagurikizukensa

jifunsagurikizukensa is also called MPT (Magnetic Particle Testing) and becomes the laboratory procedure using magnetism.
 
One becoming subject to examination becomes the materials (steel) drawn to a magnetic body, I mean magnetic force. I make use of this characteristic and let eyes detect an invisible crack and wound by letting you magnetize an investigation object and can visually observe it.

Work preprocessing

I perform the processing along the purpose beforehand to disturb that I let you magnetize wound itself when an alien substance such as paint, the rust attaches to a target mask to flaw-detect. For example, the photograph removes paint for the inspection; work.

Magnetization

I magnetize it to magnetize subjects of survey appropriately so that the direction of the wound and a direction of the magnetic flux go directly.
In the method of the magnetization, various magnetization methods are prescribed in JIS (Japanese Industrial Standards). I adopt the law between poles in us.

Adsorption of jifun

It attaches to the magnetic pole of the wound part by a wound part becoming the magnetic pole by magnetization, and spraying the special fluorescent paint consisting of magnets called jifun.

Observation of the damage part

I make it easy to let you visualize jifummoyo which it detected by the work mentioned above using ultraviolet rays signal lamp, and to observe it.

Work postprocessing

I prevent deterioration by repainting the removal, antirust treatment and paint of datsuji (I remove magnetization) and jifun as needed.
